For Example char arr[ ] = " Password"

strlen(arr) then output will be 8

Similarly we can use this to write the C boolean expression using Comparison Operator i.e <=

Boolean Expression is

strlen(password)<= 6

Above Expression is true only when length of password is 6 or fewer

This is how you can simply write a expression in One line using strlen() function .
